WHEELED PLOW.

Specification of Letters Patent.

Patented Sept. 23, 1919.

To all whom it may concern Be it known that I, HARRY S. DIGKINSON, acitizen of the United States, residing at Moline, in the county of RockIsland and State of Illinois, have invented certain new and usefulImprovements in Wheeled Flaws, of which the following is a.specification, reference being had therein to the accompanying drawing.

This invention relates to wheeled plows and has reference moreparticularly to that type of plow in which a plow frame equipped withplowing devices, is sustained by ground wheels in such manner that theframe and wheels may be moved relatively to each other to raise andlower the plows.

The object of the present invention is to provide power operatedmechanism for raising and lowering the plows, and for setting them atintermediate points to vary the depth of plowing, and with these ends inview my invention consists of mechanism of improved form by means ofwhich the adiustment of the plows is effected by power derived from thetravel of the machine through the field, suitable power controllingdevices being employed by means of which the operator or attendant maythrow the power means into action to raise the plows, may disconnect thepower means to permit the plows to be lowered, or can effectintermediate adjustments of the plows, either to increase the depth ofplowing or to diulinish the same.

ln the more specific embodiment of my invention, the frame of themachine, in the form of a single unitary structure, is equipped with aplurality of plowing devices thereby constituting a gang-plow, whichframe is supported at its front by land and furrow wheels mounted onsuitable wheel sl'lpports operatively connected together and means ofwhich the members of the clutch may be connected or disconnected atwill, the connection of the clutch causing the drum to be rotated by therotary motion of the land wheel, due to the advance of the machine inthe field, which action will wind the chain on the drum and will shiftthe wheel supports relatively to the frame and elevate the latter andthereby raise the plows and the disconnection of the members of theclutch permitting the, weight of the frame and plows to move the samedownwardly relatively to the wheel supports, thereby lowering the plowsinto action. The rear end of ,the frame is sustained by a rear furrowwheel mounted on a support movable up and 'down relatively to the frameand controlled in its up and down movements automatically by themovements of the supports for the front wheels, and in such manner thatwhen the front wheel supports are moved to elevate the plows, the rearwheel support will be likewise moved to elevate the rear end of theframe, and when the frame is lowered at the front as described, it willbe correspondingly lowered at the rear.

In the accompanying drawings I have illustrated a form of mechanismembodying the above mentioned characteristics, which in practice hasbeen found to answer to a satisfactory degree the ends and objects to beattained. It will be manifest, however, that the invention may beembodied in other and different forms and that the construction may bevariously modified and changed by the skilled mechanic without departingfrom the limits of my invention, and further it will be understood thatthe invention is not limited to any particular form or construe-- tionof the parts except in so far as such limitations are specified in theclaims.

In the accompanying drawings:

Referring to the drawings:

1 represents a suitable frame-structure,

consisting, in the present instance, of a number offore-and-aft-extending beam -members which are spaced apart and rigidlyconnected together in the form of a single unitary frame structure. Inthe particular form of the frame structure shown, three beam-members 2,2 and 2", are employed, adapted to carry plowing devices in this case inthe form of mold hoard lows, two

of the beam-members 2 and 2 being rigidly connected at their forwardends by means of a transverse connecting bar 3, and at their rear endsby a transverse brace 4. while the third beam-member 2" is connected atits front to the side of the member 2 and is connected at its rear endto the rear end of the member 2" by the transverse brace 5. This frameis sustained at its forward end by means of a land wheel 6. and a frontfurrow wheel 7, and at its rear end by a rear furrow wheel 8. The landwheel is carried by a land wheel support in the form of a crank shaftcomprising a horizontal inwardly extending shaft proper 9, a laterallyextending crank arm 9", and an outwardly extending horizontal wristportion 9 The shaft proper 9 of the crank shaft is mounted to rock inbearings 10 on the machine frame, While the land wheel is mounted forrotation on the wrist portion 9 of the shaft, the rocking of the shaftin its bearings serving to swing the wheel up and down relatively to theframe. The furrow wheel 7 is carried by a furrow wheel support in theform of a. crank shaft. consisting of an inwardly extending horizontalshaft proper 11 which extends parallel to the shaft pro per of the othercrank shaft, and which is mounted in hearings on the frame, a latcrallyextending crank arm 11". and an outwardly extending wrist portion 112the furrow wheel being mounted for rotation on the wrist portions 11,and the construction be ing such that when the shaft is rocked. thefurrow wheel will be swung up and down relatively to the frame similarto the action of the land wheel.

The two crank shafts are operatively eonnected together in such mannerthat when one is rocked, it will impart a corresponding and simultaneousrocking motion to the other, in order that the two wheels may be movedin unison relatively to the frame in raising and lowering the same andthe plows. Any suitable and appro )riate form of connection may eemployed or this purpose, but I have illustrated an adjustableconnection between the two crank shafts which forms no part of thepresent invention, but is the invention of another party, and on which aseparate application Will be filed. As shown more particularly in Fig. 1this connection is in the form of an adjusting lever 12, jointed at itsrear end to an arm 13 fixed to the end of the land wheel crank shaft,and provided with a locking latch 12 adapted to operatively engage inany one of a number of holes in an arm 14 fixed to the crank arm 11 ofthe furrow wheel crank shaft, which lever when its latch is so engaged,will form a jointed connection between the two crank shafts by which themotion of one will be transmitted to the other.

The rear furrow wheel 8 is mounted on the horizontal laterally extendingend of awheel support 15 which extends forwardly and then upwardlyvertically in the form of a journal arm 16 which is mounted to swivel inan upright bearing collar 17, the upper end of the journal arm havingfixed to it, above the collar a sleeve 18. The collar is mounted at itslower end to rock relatively to the frame on a horizontal transverseaxis, so that in the rocking motions of the collar, the wheel support.and consequently the wheel carried thereby, will. be shifted up and downrelatively to the frame. This axis is in the form of a pivot bolt 19which is passed. horizontally through two rearwardly extending bracketplates 20 bolted by upper and lower bolts 20 and 20 to the oppositesides of the roar beam-member 2*. and through a lug 17" on the collar.which lug extends forwardly between the bracket plates. The pi vota]movements of the collar to raise and lower the rear furrow Wheel, arecontrolled automatically by the up and down movements of the land andfurrow wheels at the front. of the frame. so that when the front wheelsare moved downwardlv to elevate the frame and plows at the front. therear furrow wheel will be correspondingly moved to correspondinglyelevate the frame at the rear, as will be more fully describedhereinafter.

The rocking motions of the front wheel supports to-raise and lower theplow are effected by means of power derived froin the travel of themachine through the field, the said power in the present instance beingtaken. from the land wheel by means of the mechanism now to bedescribed.

On reference particularly to Figs. 1, 5 and 6 it will be seen that thereis applied to the inner end of the hub of the land wheel 3, an outerdriving member 21 of a clutch, the inner driven member 22 of whichclutch, is loosely mounted on the wrist portion 9 of the crank shaft atthe inner end of said wrist portion. The member 21 of the clutch is inthe form of a disk provided. in its outer edge, on its inner side, withan open peripheral, lot 23. The driven member of the clutch is in theform of a disk having on its outer edge an outwardly extendingperipheral flange 24 extending within the peripheral slot 23 andadapted, when the clutch member 22 is moved outwardly, to bearfrictionally against the inner wall of the peripheral slot and efl'ect adriving connection between the two clutch members.

- sleeve 26 mounted loosely on the inner end i The driven member of theclutch is provided with -a hub constituting in effect a winding drum 25,within which extends a clutch actuating of the wrist portion of thecrank, the'said sleeve hearing at its outer end against an inwardlyextendin annular shoulder 27 on the hub of the driven clutch member andthe said sleeve being capable of a rotary oscillation on the wrist andcapable also of an driven clutch member to eifect the connection of theclutch, is effected by means of a "clutch members and maintaindisconnection endwise shifting movement outwardly to shift the drivenclutch member into engagement with the driving clutch member. As

a result of the construction described, it will 7 be understood thatwhen the landwheel is rotating, in the travel of the machine, and isimparting a corresponding rotation to the driving clutch member so that,if the driven clutch member is shifted into frictional engagement withthe other member, the driven member will be rotated with the wheel andwill correspondingly rotate the winding drum 2-5. The outward movementof the and at its inner end against the shoulder 26 on the driven clutchmember and, the tendency of the spring being to separate the thereof. Tothe winding drum 25 1s coh- 'nected the forward end of a chain 31, the

"rear end of which is connected with an arm 32 fixed to the frame of themachine, the

arrangement bclng such that when the drum is rotated, the chain will bewound thereon, and the land wheel crank shaft will be swung downwardlyand to the rear, this action effecting a corresponding movement of thefurrow wheel crank shaft, and resulting in the elevation of the frameand plows,

the motion of the drum being eifected as heretofore described by therotation of the land wheel due to the travel of the machine through thefield.

The connection and disconnection of the clutch members is effected bymeans under the control of the operator or attendant, in

the present instance the engineer of the tractor to which the plow isconnected, a rope or cord being extended from the controlling means,within reach'of the engineer to enable him to raise and lower and adjustthe plows, while at the same time he may control the tractor. Thesecontrolling means will now be described.

On reference to Fig. 1 it will be seen that there is connected fixedlywith the clutch actuating sleeve 26 at its inner end, an upwardlyextending arm 33 whose outer end is connected to a connecting rod 34,which extends iearwardly and has its inner end mounted in a slot- 35 inthe lower end of an upright clutch actuating lever 36. lever is pivotedon a horizontal transverse axis as at 37, to a stub lever 38, the innerend of which is mounted loosely on the shaft proper 9" of the land wheelcrank shaft.

The upper end of the clutch actuating lever has connected with it, therear end of an actuating cord 39 which is extended forwardly so as to beconveniently operated by the engineer or attendant. The construction issuch that when the engineer pulls forwardly on the cord, the actuatinglever 36 will be rocked on its axis, and its lower end will be swung tothe rear, which action will. through the medium of the connecting rod34, oscillate the sleeve 26, and due to the cam surface thereon engagingthe pin 29 and crank arm 9, the driven clutch member will be shiftedinto engagement with the driving clutch member, and the winding drumwill be r0- tated with the landwheel. This action will wind up thechain, and will swing the land and furrow wheels downwardly and elevatethe plows, the release of the cord permitting the spring 30 'to act anddisconnect the clutch members. The stub lever 38 is so connected with heland wheel crank shaft, that the rmking movement of the shaft willcorrespondingly rock the lever, this connection being of such characterthat the wheel will be permitted to yield upwardly relatively 1 5 to thelever in over-riding obstructions.

This connection consists of a curved strap or arm 40, the upper end ofwhich is connerted as at 41 to the stub lever, and the lower end ofwhich passes loosely through an opening This 95 in the arm 9 of thecrank shaft, a head 42 being applied to the lower end of the arm to bearagainst the rear side of the crank arm 9" and a spiral spring 43beingapplied to the lower portion of the strap and bearing at its upper endagainst a shoulder 44 thereon and at its lower end against the forwardside of the arm 9". The arrangement is such that when the crank shaft isrocked to swing the arm 9* downwardly, the stub shaft will be swungdownwardly with it, while at the same time the wheel may yield upwardlyrelatively to the shaft, against the pressure of the spring.

The stub lever eoiiperates with an upright segment frame 45 fixed to theframe of the machine, and which is provided at its upper portion with anumber of notches 46 by means of which the stub lever may be locked tohold the wheel supports in position when the plows are down in action,and provided also with a lower notch 47 by means of which the stub levelmay be locked to hold the plows elevated out of action. The stub leveris provided with a locking latch 48 cooperating with the notches, whichlatch is formed on the inner laterally extending end of a latch rod 49,extending longitudinally along the outer side of the stub lever andjointed at its rear end to the clutch actuating lever 36 at a oint abovethe pivotal axis of said lever, t e latch rod being guided in itsendwise movements, by means of a slot 50 in which the forward lateralend of the latch rod extends. The latch is acted on by a spiral spring,51 connected at its forward end to the laterally extending end of thelatch and connected at its rear end to the stub lever, and tending tomaintain the engagemerit of the latch with the edge of the segmentframe. tion, when the stub lever is swung downwardly, by the downwardmovement of the crank arm 9" to elevate the plows, and when the latcharrives opposite the lower notch, it will enter therein and the partswill be locked with the plows raised. When, however, the parts are movedin thepposite direction to lower the plow, and w en the latch arrivesopposite any one of tlie upper notches 46 in the segment frame, thelatch will enter therein and the parts will be locked with the plowsdown in action.

Due to the connection of the latch rod with the clutch actuating lever36, the operation of the latter by the cord will actuate the latch rod,and release the stub lever from Whatever position it may for the timebeing be locked 1n, the length of the slot 35 in the lower end of theactuating lever being such, inrelation to the movement of the latchnecessary to release the same, that the latch maybe actuated to releasethg lever, without actuating the clutch membol tothmnthe As a result ofthis construcclutch into action. In the operation of the parts,therefore, a slight pull on the cord will serve to release the stublever, while a greater and continued pull will serve to throw the clutchinto action, the clutch after having been once thrown into action andthe cord being released, the latch will engage one of the notches in thesegment frame, and. will lock the stub lever thereto. When the parts arein this position the slot 35 in the actuating lever will permit theclutch to be disconnected by means of the clutch spring, the end of theconnecting rod 34 in this movement being shifted-rearwardly in the slot35.

As a result of the construction. described, and of the relation of theparts stated, when the plows are down in action with the crank armsswung forwardly, and with the latch engaging one of the upper notches inthe segmerit frame to lock the parts in this position and with theclutch disconnected, if it is desired to raise the plows out of action,the operator pulls forwardly on the aetuatin cord to rock the clutchactuating lever 3 The first movement of the lever will disengage thelatch from the notch in the segment frame, and release the parts, andthe further movement of the lever, due to the continued and further pullon the cord, will rotate the clutch actuating sleeve 26 and throw theclutch into action, whereupon the motion of the land wheel being takenup b the winding drum, the chain will be wound thereon, and the crankarms will be swung downwardly and to the rear, thereby swinging the stublever downwardly and ele ating the plows. The tension on the actuatincord is maintained until the lower notch 4% of the segment frame isreached by the latch, whereupon the cord is released, which will permitthe latch to enter the lower notch and the clutch spring will act todisconnect the clutch, the result being that the plows will be heldlocked in an elevated osition. If now the plows are to be lowered intoaction, of course the clutchshould remain out of action, and therfme aslight pull is iven the cord suflici ent only to release the atch fromthe notch in the segment frame. The weight of the plow frame will nowact to lower the same relatively to the wheels, the crank arms in thisaction in effect swingin upwardly and the chain being unwount l from thedrum. Provided that the plow is tobe lowered to a considerable depth, asdetermined by any of the upper notches 46 above the lowermost notch ofthe series, the operator will hold the cord so as to maintain the latchretracted, and when the notch is reached for the proper depth of theplows, the cord is released and the latch will be forced by its springinto said notch, thereb locking the parts in the particular adjus Ill Ithe latch an position. If, however, the parts are to be ocked inposition with the latch entering thelowermost notch of the upper series,then the operator will, after releasing the latch by a Sli ht pull,immediately release the cord, and the latch travclin along the smoothedge of the segment rame as the stub lever move's upwardl will beautomatically projected into sai lowermost notch by its spring. 3 a Ifthe lows have been lowered to a certain dept as dete rmined by theengagement of the latch in one of the upper notches, and it is desiredto elevate the plows a short distance, say to the next notch, theoperator will give a strong pull on the cord so as to release ;'thelatch and throw the clutch into action, and when the proper height hasbeen reached, the cord will be fully released, w ith the result that thelatch will engage inthe new position, and the clutch will beautomatically disconnected by its spring. To restore the plows to theirformer ositioi, but a slight pull on the cord wil be i en,sufi icientonly to release without throwing the clutch in, whereupon the frame willdescend by gravity, and the cord being released, the latch will reengagethe segment frame in the original position.

It is seen, therefore, that by means of my im roved controllingmechanism, not only is it possible to raise and lower the plows to theextreme limits, but their depth, when in action, may be varied at willby the proper manipulation of the cord actuated parts, either toincrease the depth of cut or to diminish the same. This ca ability ofinter'nediatecadjustments by t e controlling mechanism is of specialadvantage in connection with tractor-propelled plows, as it is a wellknown fact that in plowing under unusual 'condi ions of soil, whichmakes the pull of the plow extremely hard, and taxes the power of thecngine to the limit, it is necessary and highly desirable to raise theplows somewhat torelieve the load, and to prevent stalling of the motoror the straining of the parts. Also when unusual surface conditions ofthe soil are encountered, on which the tractor wheels be in to slip, itis necessary to relieve the loari which may be effected by raising theplows slightly as above described, and when these conditions arerelieved. it is desirable to return to the normal depth conveniently andquickly, which action is provided for by my improved mechanism.

In order that the operator, in the operation of lowering the plows, maybe relieved of the necessity of timing the release of the latch al theprecise moment that the particular izotch for the desired depth isreached, 1 provide an adjustable stop device for limiting the upwardswing of the stub lever and consequently the depth to which the plowswill descend in the lowering action. This stop device coiiperatcs withthe segment frame in such manner that it may be set to the differenttoothed positions, to correspondingly limit the upward movement of thestub lever, and to insure the engagement of the latchin the proper notchWithout requiring the attention of the operator. A convenient form ofstop device for this purpose is shown particularly in Fig. 1 andconsists of a link or ring A. which encircles the toothed edge of thesegment frame, and is adapted to be seated in any one of the other uppernotches as desired, according to the depth to which the the extremeupper notch, the plows will be allowed to descend to the full andextreme depth, the link when engaged in the notch, being engaged by therear edge of the stub lever. and acting to limit the upward motion ofthe same. If the conditions are such as to require a diminished depth ofplowing, then the stop link will be shifted to one of the other notches,and in its new position the stub lever will be arrested as before andthe latch permitted to be actuated to hold the parts at the diminisheddepth.

The mechanism for controlling the up and down movements of the rearfurrow wheel automatically by the corresponding movements of the frontsupporting wheels, to the end that the frame as a whole will be raisrdand lowered at both ends, comprises lIltllQ present instance an uprightlever 52 pivoted near its lower end, by means of a horizontal transversepivot bolt 53, between the bracket plates 20, in advance of the rockingcollar 18 before alluded to as constituting the bearing for the rearwheel support. The lower end of this lever is in position to engage alug 5d projecting forwardly from the collar 17, and the upper end of thelever has jointed to it, the rear end of a fore-and-al'bcxtcudingoperating rod 55, the forward end of which is connected to an arm 56lixcd to and extending upwardly from the shaft proper of the land wllcclcrank shaft. When the plows are down and in action the said arm 56 willbe swung to the rear, and the weight of the rear end of the plow frame,acting on the pivotal connection of the collar 17 with the frame, thecollar will be tipped forwardly on its axis and by the engagement of thelug 5-1 thereon with the lower end of the lever 52, the latter will beinclined rearwardly at its upper end with its rear edge engaging in anotch 57 in the forward side of the sleeve 18 and in this position ofthe parts, the rear wheel will be locked from swiveling action, and willtravel straight forward in the line of draft. When now the ower liftingmechanism is operated as efore described, to swing the arms of theforward crank shafts downwardly and rearwardly to elevate the plows, thearm 56 on the land wheel crank shaft will be swung forwardly, whichaction will draw the operating rod 55, for wardly and this in turn willswing the upper end of lever 52 forwardly and its lower end rearwardly..The first movement of the lever 52 will disengage the same from thenotch in the sleeve 18, and the further movement of the lever will causeits lower end to engage the lug on collar 17, this action resulting inthe rocking of the sleeve rearwardly ()1 its pivotal axis, and themovement of the furrow wheel downwardly and the correspondin; elevationof the rear end of the frame. 'When the adjusting mechanin1 is operatedto lower the plows again, the foregoing operations are repeated, withthe result that the rear furrow wheel will be permitted to swingupwardly in effect, rrlativ ly to the frame as the latter descends, andlever 52 will again engage in the notch in the sleeve. From theforegoing description. therefore, it will be seen that when the plowsare elevated, the rear furrow wheel will be automatically released andpermitted to swivel freely, so that it may follow the path of travel ofthe plow in turning at the ends of the furrows or in transportation andwill thus facilitate the proper guidingof the machine.

The feature of thus raising the rear end of the plow is of advantageand'importance, in that in, turning at the ends of the furrows or intransportation, the plow bottoms are lifted entirely clear of theground, thus keeping them clear of trash andfree of danger of usualobstructions. Also it has the advantage of relieving the wear on theheel of the land side. which would result if the plows were draggedaround. The feature of automatically locking the rear wheel in thenormal line of travel, when the plows are lowered in action, is ofadvantage in that it is often necessary when plowing, to back the plowup to clear an o struction, or to remove trash from the bottoms and alsoto make adjustments or replacements. If, in these circumstances, therear wheel were allowed to caster or swivel, there would be nothing toprevent it from moving out of the line of travel, or from lllOVlll"sidewise into the furrow wall, or the lbwed ground, thereby renderinglia'ble, t e breakage or damage of the parts.

In order that the relation of the rear furrow wheel to the plow bottomsmay be varied or adjusted in the normal operation of plowin so that theWheel will take greater or ess pressure, I provide an adjustmg member,in the present instance in the form of a lever 54 provided with an upperarm 54", a lower arm 5i and two rearwardly extending parallel arms 54.This lever is situated between the plates 20 before alluded to, and hasits rear arms pivotally mounted on the pivot bolt 53 of the lever 52.The lower arm 54 bears against the rear edge of the plow beam, while theupper arm is provided with an adjusting screw fi l which bears againstthe rear edge of the plow beam at a point above the lower arm. Theplates 20 are slotted horizontally where the upper bolt 20 asses throughthem. so that the plates ant furrow wheel carried thereby may e tippedup and down relatively to the beam on the lower bolt 20 as an axis. As aresult of the construction described, by first loosening bolt 20 andthen screwing in the adjusting screw 54, the plates 20 and the furrowwheel will be caused to ti downwardly relatively to the beam, with t 1eefi'ect of imposing upon the wheel a greater force of pressure on theground. When the adjusting screw is turned in the opposite direction,the beam is allowed to sink. thereby relieving the force of pressure ofthe wheel. In effect the plates 20 constitute a support for the rearfurrow wheel, which support is adjustable up and down relatively to thebeam by the lever 54, and in relation to which support, the furrow wheelitself may :be moved up and down by the lever 52.

In the use of tractor drawn plows, in which the adjustment of the plowsis effected by power, it is desirable that means be provided foroperating, the adjusting means manually to raise the plows out of theground in the event that the tractor becomes stalled or is broken, whichis more apt to occur in the use of light tractors. this condition, Ipropose to utilize the stub lever for raising the plows, by a Jplying tothe lever a handle 58. The ban le may be applied as a permanentextension of the stub lever, or it may be in the form of a portabledevice to be detachably interlocked to operate the stub lever when theoccasion arises. I show the same in this latter form in Fig. 9 where itwill be seen that the stub lCWElTiS provided in its end with a notch 59,and is provided on its side with a lateral lug or pin 60, the said notchbeing ada ted to receive a lateral pin 61 on the side 0 the handle 58,and the said pin 60 being ada ted to enter a notch 62 in the inner end 0the handle when the latter is up lied to the side of the stub lover. Thee ect of the engagemcn-of the respective pins in the respeotive notches,is to effect a detachable interlorking connection of the hand lever withthe stub lever, which will enable the stub lever to be operated by hand.Vith the plows locked down in action by the latch as described, ofcourse it will be necessary To meet.

to release the latch, as by operation of the actuating cord before thehandle can be operated to raise the plows.
